BEDFORD, NH — Bedford Fire and police responded to a residence at 99-2 Pulpit Road Sunday for a report of a potential propane leak or carbon monoxide issue with victims.

Firefighters used fans and opened windows to ventilate the house and completed searches in the residence. A man and woman were located inside who were deceased, according to NH Fire Marshal Sean Toomey.

Mutual aid was requested from several fire departments for additional resources at the scene and station coverage.

Once the search was complete, the New Hampshire Fire Marshal’s Office was requested to investigate the scene.

The preliminary investigation conducted by members of the New Hampshire State Fire Marshal’s Office and the Bedford Police Department indicates carbon monoxide was a factor.

The victims were transported to the Office of the NH State Medical Examiner, where autopsies will be completed. No information on the victim’s identity has been released at this time.

The cause of the release of the suspected carbon monoxide remains under investigation. Anyone with information that may assist the investigation is asked to contact the New Hampshire State Fire Marshal’s Office at (603) 223-4289 or fmo@dos.nh.gov.

State Fire Marshal Toomey reminds all New Hampshire residents to ensure their carbon monoxide alarms work and to test them monthly. Alarm batteries should be changed during daylight saving time and any time an alarm starts chirping, which is an indicator of a low battery.

Carbon monoxide is a colorless, odorless, tasteless gas known as the “silent killer.” Signs and symptoms of carbon monoxide poisoning may include headache, weakness, dizziness, nausea, or vomiting, as well as shortness of breath, confusion, blurred vision, or loss of consciousness. Anyone experiencing these symptoms, or if a carbon monoxide alarm goes off, should exit their home, get to fresh air, and call 9-1-1 immediately so their local fire department can investigate the cause of the alarm.
